MySQL Gem for Ruby On Rails

I have searched everywhere and no ones solutions solve my problem. I have built rails apps using SQLite but not MySQL. For this particular project, I need MySQL. When I attempt to boot the server I get an error, so I attempt to install the gems for MySQL and get another error. Does anyone have any insight? Thank you!

    rails server
    Could not find gem 'mysql2 (>= 0)' in any of the gem sources listed in your Gemfile.

    sudo gem install mysql2
    Building native extensions.  This could take a while...
    ERROR:  Error installing mysql2:
        ERROR: Failed to build gem native extension.

            /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
    mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h


    Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/mysql2-0.2.7 for inspection.
    Results logged to /Library/Ruby/Gems/1.8/gems/mysql2-0.2.7/ext/mysql2/gem_make.out

I had this problem. You need to install the mysql gem with native extensions.

The line you're probably looking for is this:

$ ARCHFLAGS="-arch x86_64" gem install mysql2 --version '~> 0.2.7' -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
